Answer:

4.Side Side Angle Congruence (SSA)

5.Corresponding Parts of Congruent Triangles

Step-by-step explanation:

Statement

$\bigtriangleup BAD\:\cong\bigtriangleup CAD$

Reason

4.Side Angle Side Congruence (SSA)

Explanation:

Two triangles are congruent by SSA if two respective sides and one respective angle are congruent. In this case, ∠ A for both triangles.

Statement

$\overline{BD}\cong \overline{CD}$

Reason

5. Corresponding Parts of Congruent Triangles

Since these triangles are congruent by SSA congruence they have corresponding sides: BD and DC. BD and DC are one of the corresponding parts of these congruent triangles sharing the same measure.

Given the m<8=45, find the other angle measures. Be able to say how you found each angle measure. PLEASE help!

iris [78.8K]

Answer:

m<1 = 135°, m<2 = 45°, m<3 = 135°, m<4 = 45°, m<5 = 135°, m<6 = 45°, m<7 = 135°

Step-by-step explanation:

We know that a straight line always gives us a measure of 180° total. This would mean 180° = m<8 + m<7. So, if we plug in the real value of m<8, we get 180 = 45 + m<7. From there, we can subtract 180 by 45, and we get 135° = m<7.

We know that vertical angles are congruent - so m<5 is the same as m<7 - making m<5 = 135° as well. This could also apply to m<8 and m<6, so m<6= 45°.

From there, we can also say that alternate interior angles are congruent to each other - meaning m<5 = m<3, and m<6 = m<4. So, m<3 = 135° and m<4 = 45°.

Alternate exterior angles are congruent too, which means m<8 = m<2, and m<7 = m<1. So, m<2 = 45° and m<1 = 135°.

In summary,

m<7 = 135° because angle subtraction.

m<5 = 135° and m<6= 45° because vertical angles are congruent.

m<3 = 135° and m<4 = 45° because alternate interior angles are congruent.

m<1 = 135° and m<2 = 45° because alternate exterior angles are congruent!

Hope this makes sense! Not sure if I explained it well.

What is the constant of proportionality in the equation y=x/9?

sesenic [268]

Answer:

1/9

Step-by-step explanation:

Separate the fraction (1/9) from the variable x:

y = (1/9)x.

1/9 is the constant of proportionality.

Convert each percent into a fraction and decimal:<br> 133 1/2%<br> 87 1/3%<br> 0.01%<br> 8 1/3%

Elis [28]

Answer:

267/200 = 1.335
131/150 = 0.8733...
1/10,000 = 0.0001
1/12 = 0.0833...

Step-by-step explanation:

It might be helpful to think of the % symbol as being interchangeable with /100.

133 1/2% = (133 1/2)/100 = 267/200 = 1.335

87 1/3% = (87 1/3)/100 = 262/300 = 131/150 = 0.8733333... (repeating 3)

0.01% = 0.01/100 = 1/10000 = 0.0001

8 1/3% = (8 1/3)/100 = 25/300 = 1/12 = 0.0833333... (repeating 3)
